Sony MDRNC500D (Black)
Black digital noise-cancelling headphones
The world's first headphones to use "digital feedback noise-canceling technology." Sony MDR-NC500D headphones minimize stress on eardrums, while canceling up to 99% ambient noise. Headphones assess and adjust to environmental noise in three modes, while maintaining crisp digital sound quality. Further, a unique Monitor switch lets you cut the music and zero-in on surrounding sounds, all without removing the headphones.
